  • a room conditioning system for permanent living rooms or similar.
  • This comfort zone and the limits of safe air composition were determined in scientific studies and are named as a function of different parameters (activity level of the person, use of space, etc.) in various standards, guidelines and ordinances (e.g. [1] - [4]).
  • Design features that enable the integration of low-priced environmental energies have been taken into account in heating and air conditioning systems that are common today.
  • One of these features is the use of large heat transfer surfaces in order to manage with low system over or under temperatures (e.g. combined heating and cooling ceilings). This makes it possible, for example, to utilize the thermal level of groundwater or surface water to cool the room, or to effectively use condensing heating technology or heat pump technology. System temperatures close to the ambient temperature result in low distribution losses and a large self-regulating effect.
  • Another characteristic of the use of renewable energies in building technology is the use of storage to compensate for a time discrepancy between energy supply and demand.
  • thermal component activation plastic pipes are usually laid in large-area, heat-energy-storage-capable components, after rare suggestions also in several different layers.

Very great demands are made on the planning and control of this system in the event that it is also to be used in the transition period. These times are characterized by the fact that the demand for heating rooms can be changed to cooling during the course of the day. Losses can hardly be avoided due to the stored energy if these requirements are to be met with the pipe systems installed in the components.
  • Air-guiding systems are also known, which can be classified under the generic term thermal component activation.
  • Special system pipes are installed in solid components, which are provided with ribs on the air side to improve heat transfer.

  • This method is often used because, in addition to a possible inexpensive energy supply and distribution, the manufacturing costs are also relatively low.
  • Latent-storing materials are substances or mixtures of substances that undergo a phase change at a certain temperature or within a desired narrow temperature range - generally between liquid and solid, but also between ordered and disordered lattice structures (OD transitions) - and thereby absorb energy or give off, this amount of energy is significantly greater than that which is necessary for a slight temperature increase or cooling outside the phase change range.

  • An advantageous embodiment of the invention consists in that the heat transport medium is heated in process step a) by solar collectors.
  • the object of the invention is achieved by a method for parameterizing systems with latent storage materials in that the devices according to the invention are also parameterized using the method.
  • the method consists in that a combination of building simulation program and three-dimensional flow simulation program is carried out in such a way that a) a building simulation program runs through a settling phase with a length of time greater than 1 day and b) in a subsequent simulation phase an automated data exchange between a building simulation program and a three-dimensional one Flow simulation program takes place and that c) during the data exchange, time-dependent conditions on the edges of the calculation areas for temperatures, heat flows or combinations thereof are exchanged, in particular the exchange of thermal boundary conditions of the 1st, 2nd or 3rd type and that d) the time step size used for the data exchange results from the conditions for a stable explicit calculation or from an algorithm-related or programmatically possible time step size, which also results in a repeated iteration on and thus comparison of the balanced amounts on the boundaries of the calculation areas allowed.
